LSB based Audio Steganography for Enhancement in Security Matlab Project with Source Code || IEEE Based Project

ABSTRACT

               Steganography is one of the best data hiding technique in the world which can be used to hide data without its presence felt. In today’s digital world most of us communicate via use of electronic media or internet. Most people among us remain unaware about the data loss or data theft which can happen on online transmission of data or message. Valuable information including personal data, messages transmitted through internet is vulnerable to hackers who may steal or decrypt our data or messages. This poject is about enhancing the data or message security with use of Audio Steganography using LSB algorithm to hide the message into multiple audio files. The message hidden by this application is less vulnerable to be stolen than other similar applications. This is due to following reasons: Firstly files are taken to hide high amount of message which enhance information hiding capacity. Secondly before being hidden, the message is broken into parts and shuffled randomly based on permutation generated at runtime so even if the LSB gets encountered the message is still unarranged and meaningless which enhances its security. This application is capable to carry large amount of information with greater security. 

                 As world is changing fast, people wants to save their time and resources to keep pace with the fast growing technology for the fulfillment of their needs. As internet has become a working need of the people like electronic banking, mobile banking, online shopping, transferring data from one place to another, gathering or retrieving of information. Data Security need is also increasing due to risk of theft, hacker, intruders, eavesdroppers, sabotage and unauthorized user. Security can be achieved using cryptography which encrypts message and make it unreadable from unauthorized people or watermarking technique provides copyright protection and the third one is steganography. Steganography is a uniquetechnique coming from old times which help user to hide their critical information without creating any suspicion. Information hiding can be done in various cover mediums like image, audio, video, text etc. Cover is chosen according to the need like audio steganography is an interesting medium because latest song or famous songs can be used to hide messages. Embedding techniques are chosen according to requirement. Some of the techniques are LSB coding, parity coding, phasecoding, spread spectrum and echo hiding. It can be used for hiding any information like secret formulas, images,private communicationand forensic authentication. As audio steganography uses audio as a cover medium,similarly this application too uses an audio as a platform for hiding the message. User provides input message in the form of text and chooses the audio wave file to hide the message. This application provides a smart and interactive interface for message hiding and its retrieval. Message is shuffled in random sequencebefore being hidden. Random sequence which is generated based on certain factors is used to shuffle the message before hiding it. This further enhances the data security.
